I've been playing squads as defensive coach and sometimes the HC in the game seems to be able to adjust my preplay stuff. He can take his position out of the blitz I put him in or he can put a lineman in a spy. How is this possible? I thought I controlled it but apparently not?
No matter the position I play I always put at least on lineman on a spy if the opposing QB is a good scrambler (unless it's like a 4th and forever in which case it is unlikely the QB would be able to get to the first down marker even if he did run with it.) The blitz is just never guaranteed to get there fast enough and if they get a chance to run with it they will. Some defensive captains might not like it (I don't know I never ask) but I've been burned by it too many times to just go full blitz.
